Patent number: 11072846Abstract: A method for hot-dip coating of a steel strip running in a bath of liquid metal such as zinc, or metal alloy contained in a pan is provided. Dross which are formed during the coating and float at the surface of the bath are moved away from the surface of the strip by at least one inductor. Each inductor produces a sliding electromagnetic field oriented along a given direction and generates a magnetomotive force, and the magnetomotive forces displaced the dross towards a container intended to collect them and/or towards an area of the surface of the bath from which they are discharged. For at least one of the inductors, the direction of the respective sliding electromagnetic field is reversed intermittently so as to modify the flows of the dross inside the pan. A hot dip coating facility is also provided.Type: GrantFiled: March 2, 2017Date of Patent: July 27, 2021Assignee: ARCELORMITTALInventors: Marc Anderhuber, Alain Daubigny

Publication number: 20100237066Abstract: Yoke formed by a stack of magnetic laminations 4 that have mutually parallel edge notches 7 with open lips, these being located at least in the corners of the inductor. These notches are preferably spaced apart by a few mm, but the separating interval may be higher, from 1 cm and beyond, without however exceeding about 5 cm. They start at the lamination edges and extend, preferably along straight lines, towards the interior over a distance that depends on the environment of the inductor. They are produced by removing material so that each notch 7 has non-touching lips (therefore open lips), even preferably at discrete points, so as to prevent offering bridges for the circulation of eddy currents thereat. The invention applies to the production of heating inductors, by controlling the thermal behaviour of the inductors by simple means that prevent them from overheating.Type: ApplicationFiled: September 18, 2008Publication date: September 23, 2010Applicants: ArcelorMittal France, Arcelormittal-Stainless FranceInventors: Alain Daubigny, Marc Anderhuber

Patent number: 6498328Abstract: A heating device for the electromagnetic induction heating of a metal strip traveling in a specified direction. The device includes at least one electric coil arranged opposite at least one of the large surfaces of the strip so as to heat the latter by transverse magnetic flux induction, each coil being associated with at least one magnetic circuit. Each circuit is divided into a plurality of magnetically independent bars arranged parallel to the direction of travel of the strip. The bars may moved toward or away one another thereby adapting to the width of the strip and distributing the magnetic flux across the width of the strip.Type: GrantFiled: April 5, 2001Date of Patent: December 24, 2002Assignees: Celes, Usinor, Electricite de FranceInventors: Marc Anderhuber, Jean-Philippe Chaignot, Claude Couffet, Jean Hellegouarc'h, Bernard Paya, René Pierret, Yves Neau, Jean-Camille Uring, Olivier Pateau, Gérard Griffay, Alain Daubigny, Philippe Roehr
